<p>So FYI I just r+'d the PR that <span class="user-mention" data-user-id="123586">@nagisa</span> opened (<a href="https://github.com/rust-lang/rust/issues/54640" target="_blank" title="https://github.com/rust-lang/rust/issues/54640">#54640</a>) to backport the removal of "noalias" to beta. I <strong>believe</strong> that was what we said in the weekly meeting before — in particular, because this was a soundness fix.</p>
